An electronic question-and-answer device includes a keyboard on which codes associated with questions and answers may be entered. The device also includes indicator lights and a sound-generating device for indicating whether the correct answer has been entered on the keyboard. Circuitry is included that interprets the question code and answer code as numerical values and compares the numerical values entered thereby. In order that different correspondences between question codes and answer codes can be used with different sets of questions and answers, each set of questions and answers is provided with a different key-defining connector that connects the keyboard and internal circuitry in such a manner as to define the number entered by a given key. |
